  • an improved coupling component or yoke 52 is connectable with different size force transmitting members.
  • the coupling component or yoke 52 may be connected with the input shaft 24, the tubular force transmitting member 40 in the variable length shaft 26, and the tubular force transmitting members 46 and 48 in the variable length shaft 32.
  • two coupling components 52 are used in the coupling assembly 30.
  • a coupling component 52 is used in each of the coupling assemblies 34 and 36.
  • the coupling assembly component 52 can be connected with force transmitting members of different sizes and constructions.
  • the coupling component 52 can be connected with the solid input shaft 24.

  • the arms 58 and 60 are integrally formed as one piece with the base 56.
  • the base 56 (FIGS. 2 and 3) of the coupling component 52 to be connected with either the tubular force transmitting member 40 or 46, the base 56 has a large diameter, cylindrical, radially outward facing mounting surface 64.
  • the base has an intermediate diameter, cylindrical, radially outward facing mounting surface 66.
  • the base has a small diameter, cylindrical, radially inward facing mounting surface 68.
  • the mounting surface 68 defines a passage which extends axially through the center of the base 56.
  • the mounting surfaces 64, 66 and 68 are disposed in a coaxial relationship. However, the mounting surfaces 64 and 66 are axially offset from each other. Thus, the mounting surface 66 is disposed axially outward of the mounting surface 64.
  • Stop or locating surfaces are associated with each of the mounting surfaces 64, 66 and 68 to facilitate axial positioning of force transmitting members relative to the base 56.
  • a flat annular stop or locating surface 72 extends radially outward from the large diameter mounting surface 64 (FIGS. 2 and 3) and is engageable with a circular end surface on the large diameter force transmitting member 40 or 46.

  • the mounting surface 68 could be formed on a relatively small diameter projection from the main section 80 of the base 56. If this was done, the mounting surface 68 would be used with relatively small diameter tubular force transmitting members rather than a solid shaft, such as the input shaft 24. By forming the mounting surface 68 with the radially inward facing orientation illustrated in FIG. 3, the mounting surface can be used to engage an outer side surface of a solid shaft rather than an inner side surface of a tubular shaft.
  • FIG. 4 The manner in which the coupling component 52 is connected with the force transmitting member 40 is illustrated in FIG. 4.
  • the large diameter mounting surface 64 is inserted into the large diameter force transmitting member 40. This results in a cylindrical inner side surface 84 on the large diameter cylindrical end portion 41 of the force transmitting member 40 being disposed in telescopic abutting engagement with the large diameter mounting surface 64.
  • a flat annular end surface 86 on the cylindrical end portion 41 of the force transmitting member 40 is 5 disposed in abutting engagement with the stop surface 72 to position the coupling component 52 axially relative to the force transmitting member 40.

  • the intermediate mounting surface 66 is inserted into the small diameter cylindrical end portion 49 of the force transmitting member 48. This results in a cylindrical inner side surface 94 on the small diameter force transmitting member 48 being disposed in telescopic abutting engagement with the intermediate diameter mounting surface 66 on the base 56 of the coupling assembly component 52.
  • a flat annular end surface 96 on the small diameter force transmitting member 48 is disposed in abutting engagement with the stop surface 74 to position the coupling component 52 axially relative to the small diameter force transmitting member 48.
  • An annular weld 100 interconnects the coupling component 52 and the small diameter force transmitting member 48. At this time, a longitudinal central axis of the small diameter force transmitting member 48 is coincident with the central axis 92 of the coupling component 52.
  • the input shaft 24 has a solid construction with a cylindrical body section 104 and a cylindrical end section 106 which are disposed in a coaxial relationship.
  • the end section 106 is telescopically inserted into the cylindrical small diameter mounting surface 68 which extends axially through the base 56.
  • a cylindrical outer side surface 110 on the end section 106 is disposed in telescopic abutting engagement with the small diameter mounting surface 68 on the base 56 of the coupling component 52.
